Tim Kaiser makes amazing instruments from old-retroy gear! He writes –

Some of these devices and instruments are in my personal stage set-up. The rest are owned by other musicians and artists around the world. I regularly take commissions for new work-

Some devices can be roughly duplicated, but they are all built one-at-a-time and pretty much one-of-a-kind. Some of the effects are modified existing circuits re-housed into a vintage piece of test gear or what have you. Others are fully original designs.
